CROSS-REFERNCE TO RELATED APPLICATIONS

[0001] This is a divisional of U.S. patent application Ser. No.10/159,634 and claims benefit to U.S. Provisional Application No.60/364,554, both of which are hereby incorporated by reference herein.

BACKGROUND OF THE INVENTION

[0002] The present invention relates generally to golf carts, also knownas golf cars, and other small trunkless motorized vehicles.

[0003] On a golf course, golfers often carry their own golf clubs in agolf club bag. The golfers may walk the entire course with the golf clubbag held by a strap swung over their shoulder. A typical set of golfclubs may include 12 golf clubs or more. The set of clubs thus is oftenheavy and cumbersome to carry over an entire course. A caddie mayaccompany the golfer to aid in carrying the golf clubs.

[0004] Wheeled golf club carriers, also known as pull carts, have beendeveloped to permit golfers to wheel their clubs over the course, bypulling the carrier by hand. The golf club carriers typically permit agolf bag to be attached by straps, and the golf bag is thus transportedover the entire golf course by the golfer pulling or pushing thecarrier. Such manual golf club carriers and the associated walking ofthe entire course however lead to slow golf games, which can be a majorproblem on popular golf courses. Moreover, some golfers fatigue or areincapable of walking an entire golf course, which can require 4kilometers of travel or more.

[0005] Motorized golf carts, typically having electric orinternal-combustion motors, also are known. Some courses even requiresuch carts to speed golf play. These motorized golf carts typically movealong specially-designated areas, or cart paths, on the golf course sothat golfers can proceed with ease quickly throughout the golf course.Some golf courses permit golf carts to travel not just on the cartpaths, but also over the entire course, including fairways. However,this travel can damage the golf course. For example, when a fairway iswet, the golf carts can leave muddy track marks on the fairway or evenon the greens. For this reason, many golf courses confine motorized golfcarts to the cart paths.

[0006] When using a motorized golf cart, golfers typically place theirgolf bags in the golf cart and strap them in. They do not remove thebags during play, since the bags with the clubs are heavy and the golfbag must be lifted to be strapped in. Typically, the bottom of the bagsits at least 0.3 meters from the ground, and the straps are evenhigher. The lifting of the golf bag in the first place is alsoburdensome.

[0007] On a course where the motorized golf carts are confined to thecart paths, golfers without caddies typically golf as follows: (1) Thegolfer drives his cart to a tee, decides what club to use and removesthat club from the golf bag located in the golf cart, and then tees off;and (2) the golfer then drives the cart along the path to a locationnear the golf ball, guesses which one or two clubs might be proper,removes the clubs from the golf bag situated or attached to the golfcart; and then walks to the golf ball with the clubs in hand, and hitsthe ball. This second step continues until the golfer has placed theball in the cup.

[0008] A problem occurs when a golfer selects the wrong club or clubsfrom the bag in the motorized cart. Improper selection can occur forexample because of the lie or by mistaking the distance of the ball orthe wind speed at the location of the ball. The golfer then must walkback to the cart and replace his clubs with a proper club. Since hisball may be a long distance from the golf cart, a long delay can result.Moreover, the partner in the motorized golf cart, which typically hastwo seats, could have driven the motorized cart to a new location,leading to even longer delays.

[0009] If two players are using a motorized cart on a golf course wheremotorized carts are permitted on the fairway, a similar problem mayoccur: the first golfer may choose one or two clubs, and the secondgolfer will drive the cart to a new position. If the first golfer haschosen the wrong clubs and must return to the golf cart at a newlocation to exchange clubs, the speed of play can be drasticallyreduced.

[0010] U.S. Pat. No. 5,472,084 discloses a piggyback golf bag for use ina riding golf cart. An attachment device can connect the golf bag to thegolf cart. The golf bag when attached to the golf cart rides in acompartment and must be lifted onto the golf cart.

[0011] U.S. Pat. Nos. 6,193,256 and 5,482,304 disclose trailer devicesfor golf equipment. The golf equipment trailer of the '256 patent doesnot function as a golf club carrier, which is defined herein as amanually-movable golf club carrier, such as push or pull cart. Thepull-type golf cart of the ′304 patent is attachable solely to abicycle, and appears not to be intended to be detachable during play butrather that the bicycle be ridden on the golf course.

[0012] U.S. Pat. No. 6,238,171 discloses a portable towing apparatusfitting in the golf bag bay of a golf cart for towing another disabledgolf cart.

SUMMARY OF THE INVENTION

[0013] In light of the problems associated with motorized golf carts,the present applicant disclosed motorized golf carts provided withhitches in U.S. patent application Ser. No. 09/924,039 filed Aug. 7,2001 and U.S. patent application Ser. No. 09/961,882, filed Sep. 24,2001, both of which are hereby incorporated by reference herein. Wheeledpull carts can be attached to the hitches. Through spring forces, forexample, energy may be stored to assist the golfer in raising the centerof gravity of the pull cart and to lift the wheels.

[0014] An object of the present invention is to permit golfers to moreeasily attach a golf club carrier, such as a pull cart, to a motorizedgolf cart. Another alternate or additional object is to providemotorized golf carts with the capability for easily attaching all typesof detachable devices to the golf cart. Still a further alternate oradditional object of the present invention is to reduce the amount oflifting required to attach golf club carriers or other devices to themotorized golf cart. One other alternate or additional object of thepresent invention is to speed the play of golf on a golf course.

[0015] The present invention provides a motorized golf cart having amotor for driving the golf cart, a motorized actuator and a firsthitching device, the actuator connected to the first hitching device formoving the first hitching device between a first position and a secondposition.

[0016] By having a motorized actuator move the hitching device, variousdetachable devices can be attached to the hitching device and lifted bythe actuator, without any manual lifting force being required.

[0017] Preferably, the motorized golf cart includes a detachable devicewith at least one wheel, the detachable device being connectable to thefirst hitching device in the first position, the at least one wheelbeing retracted in the second position. “Retracted” as defined hereinmeans that the wheels are not in contact with the ground.

[0018] Preferably, the detachable device is a manually-operable golfclub carrier having a carrier hitching device for attaching to the firsthitching device when the first hitching device is in the first position.The golf club carrier thus can be easily attached and detached to themotorized golf cart, using the actuator and without any lifting, as thegolf cart is driven and then stopped at various points along a cart pathor anywhere on the course. The golfer can unhitch the golf club carrierby reversing the actuator and wheel it, along with all the golfer's golfclubs, to a desired location on the course. Any club can be selected.The first golfer's companion, if any, in the golf cart can drive thecart on to the next desired location, without worrying that the firstgolfer will need to return due to improper club selection. The firstgolfer can then wheel the golf club carrier to the next ball location orback to the motorized golf cart, where it can be easily reattachedwithout lifting.

[0019] Advantageously, with the hitching devices of the presentinvention, other detachable devices with at least one wheel may beattached to the first hitching device and lifted. Thus, shopping carts,specialized carts for garden tools, wheelchairs, and other devices maybe interchanged and carried by the golf cart. The actual sizes andlimits of the detachable devices is a function of the rating of theactuators and the weight and center of gravity of the detachabledevices. The detachable devices may include a further hitching devicefor connecting to the first hitching device.

[0020] The first hitching device may include at least one bracket andthe further hitching device may include a horizontal bar. However, theterm hitching device as defined herein is any device operable forsecuring the detachable device.

[0021] The motorized golf cart preferably has two seats, and fourwheels. The golf club carrier preferably includes a golf club bagremovable from the carrier body, although the bag may be integrated withthe golf club carrier.

[0022] Preferably, the golf cart includes a second hitching device, anda second actuator for moving the second hitching device between a thirdposition and a fourth position. Thus two detachable devices can beselectively attached to the golf cart.

[0023] Preferably, the golf cart has a rear bag bay, and the firsthitching device and first actuator attach to the golf cart in the rearbag bay. The second actuator and second hitching device also may fitinto the rear bag bay.

[0024] The first and second actuators preferably are motorized linearactuators. Preferably, the linear actuators are powered by arechargeable battery, for example the battery of the motorized golf cartor separate batteries provided for the actuators. Most preferably, theactuators are dc motor powered linear ball screw actuators. The presentapplicant has found that Linak LA-31 electrically-driven fast motoractuators with a 150mm stroke, available commercially from LINAK U.S.,Inc., 2200 Stanley Gault, Pkwy, Louisville, Ky. 40223 are possibleactuators for use with the present invention.

[0025] Other possible motorized actuators can include: air-cylinderdriven actuators receiving compressed air from an on-board compressor orsmall tank of compressed air charged, for example, daily; an actuatorwith an hydraulic cylinder with a hydraulic motor or pump, or aretractable cable-based actuator.

[0026] The detachable devices preferably include at least a framesection made metal, such as aluminum or steel, to improve stability.

[0027] The first hitching device preferably is rotatably connected tothe golf cart around a first axis, and the first actuator rotates thefirst hitching device about the first axis. Preferably, the secondhitching device also is rotatable about the first axis, through thesecond actuator.

[0028] The first hitching device may extend beyond the rear of the golfcart, and be located at the rear of the golf cart. The first positionthen preferably is located further away from a center of the golf cartthan the second position, so that the first hitching device may pulledinwardly by the actuator so as to lift the detachable device.

[0029] Preferably, a switch is provided to actuate the actuator to movebetween the first and second positions. The actuator also can beactuated to move from the first position to the second position bycontact of the hitching device with the detachable device.

[0030] The present invention also provides a mountable actuating devicefor motorized vehicles comprising: a frame, a first hitching device anda second hitching device movable with respect to the frame, a firstactuator connected to the frame for moving the first hitching devicebetween a first position and a second position, and a second actuatorconnected to the frame for moving the second hitching device withrespect to the frame between a third position and a fourth position.

[0031] With the mountable actuating device of the present invention, thedevice can be easily pre-assembled and placed on a motorized vehiclesuch as a golf cart.

[0032] The actuating device preferably includes attachment devices, forexample nuts and bolts, so that it may easily be retrofitted to existinggolf carts, preferably in the bag bay. Preferably, the attachmentdevices include two bracket assemblies for connecting to bag holderframes of the golf cart.

[0033] The actuators preferably are linear motorized actuators poweredby a rechargeable battery.

[0034] The present device could be used with other vehicles other thangolf carts. The present invention thus also provides a motorized vehiclecomprising: a motor, a rechargeable battery, a hitching device and anactuator driven by the battery, the actuator moving the hitching devicebetween a first position and a second position. The rechargeable batterymay be an additional battery to the battery of the motorized vehicle, orthe same, if the vehicle already includes a rechargeable battery. Asecond actuator may also be provided.

[0035] The present invention also provides a method for connecting awheeled detachable device to a motorized golf cart comprising the stepsof wheeling the detachable device aside the motorized golf cart,connecting the detachable device to the motorized golf cart while the atleast one wheel remains on a ground surface, and actuating an actuatorto retract the at least one wheel off the ground surface.

[0036] The wheeled detachable device preferably is a golf club carrier,which may be unhitched from the motorized golf cart repeatedly overduring a golf game.

[0037] In addition to the advantages of the present invention enjoyed bythe golfer, the golf course operator employing the present inventioncan: (1) maintain a well-groomed course by restricting ride carts to thepaved paths or only to 90° fairway angles; (2) improve the pace of play(more golfers per day means more money per day) by enabling golfers tohave ride cart speed with golf club carrier access; (3) charge anadditional fee for the golf club carrier attachment, since the ridecarts can be operated with or without the pull cart attachment; and/or(4) attract golfers to the course by offering improved access andconvenience over the course.

[0038] The present invention also has the added advantage that afoursome golfing with two carts can switch partners easily andrepeatedly throughout a golf game. For example, a first golfer and asecond golfer have carriers attached to one golf cart, and a third andfourth golfer have carriers attached to the second cart. The firstgolfer and second golfers hit balls near the ball of the third golfer.The fourth golfer's ball is further away. The first golfer and secondgolfers can drive to near their balls, and release their carriers. Thefourth golfer can drop off the third golfer, who detaches that golfer'scarrier. The fourth golfer can proceed further. Any of the first, secondand third golfers, perhaps the one closest, can then later join up withthe fourth golfer and the second golf cart and reattach the golf bagcarrier. When playing a foursome (or threesome), this arrangement alsoeliminates worry about the pairing of golfers in the golf carts at thestart of the game, since the golfers may switch carts easily. Also speedof two-cart play can be significantly increased, since players canreturn to the closest cart.

[0039] The present invention also encompasses a detachable device forconnecting to a motorized hitch comprising a frame; a handle mounted tothe frame; at least one wheel mounted to the frame; and a hitchingdevice connected to the frame, the hitching device including a firstmount tube horizontal to the ground and a second mount tube parallel tothe first mount tube, or including a double claw hitching device.

[0040] The present invention also encompasses a detachable shopping cartfor connecting to a motorized hitch comprising a frame; a handle mountedto the frame; at least one wheel mounted to the frame; a carryingsection for groceries or goods, and a hitching device connected to theframe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0061] The present invention will be described with reference to apreferred embodiment.

[0062]FIG. 1 shows, in schematic form, a motorized golf car or cart 300having a motor 52 with an axle 56 driving front wheels 58, 60 of thecart 300. The motor 52 may be any type of motor, for example electric orinternal combustion driven. The cart 300 also has a battery 54, whichpreferably is rechargeable. The cart 300 is an existing cart having agolf bag bay 301, which has been retrofitted with an actuating device250. Attached to the actuating device are detachable devices, includinga shopping cart 201, and a wheeled golf club carrier 1. Shopping cart201 may have a square shaped holder for two shopping bags 202, 203, forexample. The golf cart 300 also has rear wheels 62, 64 and a first seat68 and a second seat 70. The motor 52 also could drive rear wheels 62,64, and first seat 68 and second seat 70 may be side-by-side in the formof a single bench seat.

[0063] An electrical circuit from battery 54 may power actuators 11,111, with actuator 11 permitting lifting and releasing of detachableshopping cart 201, and device 111 permitting lifting and releasingdetachable golf club carrier 1. An electrical supply line 502 may poweractuator 11 and supply line 506 may power actuator 111. A switch 500,with an up/down knob 501, may raise or lower shopping cart 201 and aswitch 503 with an up/down knob 505 may raise or lower golf club carrier1, or other detachable devices.

[0064] The Linak LA-31 electrically-driven fast motor actuatorsdiscussed above, for example, run on 24 volts, so that four 6 voltrechargeable batteries, often present in existing electrically-drivenmotorized golf carts can be used to power the actuators. The connectingof the electrical circuit thus may be accomplished by accessingrechargeable batteries of the electrically-driven golf cart andconnecting one wire to a negative terminal of a first battery and theother wire to a positive terminal of a fourth battery. If the golf cartis internal combustion driven, rechargeable batteries may be providedseparately.

[0065] As shown in FIG. 2, the detachable devices may also be twowheeled golf club carriers 1, 101. Wheeled golf club carrier 1 haswheels 4, 34 and a carrier hitching device 20 having a first mount tube2 and a second mount tube 3. Carrier 1 includes a golf bag 5, which isattached by a golf bag holder or straps. As shown in FIG. 6, eachwheeled golf club carrier 1 has a handle 7, golf bag holders 6, 16,wheels 3, 34, and a main frame 9. Carrier hitching device 20 has mounttubes 2, 3, which have end caps 8, 18 and 28, 38 respectively. The partsof carrier 1 are all fixed to each other, except that holders 6, 16 canbe tightened, and wheels 4, 34 are rotatable.

[0066] As shown in FIG. 2, carrier 101 may be identical to carrier 1,and have a golf bag 105, an upper mount tube 102 and a lower mount tube103.

[0067] Carrier 1 is detachably connected to a lift bracket 10, which canrotate about an axis A-A. Above the axis A-A, the bracket 10 isconnected to a linear actuator 11, which can rotate the bracket 10 aboutaxis A-A. The other end of actuator 11 is connected rotatably to aactuating device frame 200, which is attached via a bracket assembly 201to a bag holder frame 302 of golf cart 300. Another bracket assembly 204connects to another bag holder frame 402 of golf cart 300.

[0068] Second carrier 101 is detachably connected via tubes 102, 103 toa second bracket 110, also rotatable about axis A-A. Brackets 10, 110thus defined hitching devices for hitching the carriers 1, 101 to thegolf cart 300.

[0069]FIG. 3 shows more detail of frame 200 of the actuating device 250.Second actuator 111 is connected to mount bracket 110, so as to enablemount bracket to selectively rotate about axis A-A.

[0070]FIG. 4 shows the actuating device 250 in more detail. Frame 200may include a foot plate 202, which may be attached by bolts 203 to thebag bay 301 (FIG. 2), for example though water drainage holes. Nuts maybe used to fasten the bolts. Device 250 thus is easily mountable in thegolf bag bay 301 using brackets 201, 204 and bolts 203.

[0071] The mount bracket 10 preferably has an upper claw 12, and a lowerclaw 13. Attached to the mount bracket 10 at one side is the actuator11, which may be pivotally connected about an axis D. The other end ofactuator 11 may be pivotally connected to frame 200 about an axis B.

[0072] Likewise, second actuator 111 may be pivotally connected to frame200 about an axis C, and to a side of mount bracket 110 about an axis E.When actuator 11 and actuator 111 are in a same position, axes D and Epreferably are coaxial, as are axes B and C.

[0073] Frame 200 preferably is made of metal, although it could also bemade of high-grade plastic.

[0074]FIG. 5 shows a convention rear of a golf cart 300 with a bag bay301, without retrofitting with actuating device 250. Golf cart 300 has abumper 303.

[0075]FIGS. 7 and 8 show the golf club carrier 1 attached in theretracted position to the first hitching device comprised of liftbracket 10 in its second or retracted position. Upper mount tube 2 fitsin upper claw 12, and lower mount tube 3 fits in lower claw 13. Thesecond hitching device and second actuator of the actuating device, aswell as golf bag 5, are not shown in this view for clarity.

[0076] Lower claw 13 preferably is spaced from upper claw 12 so thatwhen upper mount tube 2 is located fully fit in upper claw 12, lowermount tube 3 can rotate freely into and out of claw 13, although asshown in FIG. 8, the weight of carrier 1 causes a torque about tube 2that holds mount tube 3 firmly in claw 13. However, the lower mount tube3 may be sized to just pass into claw 13 with a slight friction fit asit passes a front finger 113 of claw 13. Tube 3 may include a frictionreducing element, such as a plastic wheel or Teflon-coating at thecontact point with finger 113 of claw 13.

[0077]FIG. 9 shows golf club carrier 1 being lowered, for example by agolfer lowering knob 501 of switch 500 (FIG. 1). Linear actuator 11 thusextends in the direction of the arrow J, causing lift bracket 10 torotate in the direction of the arrow H about axis A. Mount bracket 10can for example be mounted with a bearing on frame 200, which includes abar coaxial with axis A. Thus, the first hitching device is between thesecond position shown in FIG. 8 and a first position where the linearactuator is fully extended. The wheel 4 however remains off of ground400.

[0078] As the claw 12 of bracket 10 rotates in direction H, torquecaused by the weight of carrier 1 keeps mount tube 3 in claw 13, since aclockwise torque as shown in FIG. 9 is created about mount tube 2.

[0079]FIG. 10 shows the actuator 11 before its first or fully extendedposition. As shown in FIG. 10, wheel 4 contacts ground in this position,but frame 9 remains above ground. Upper mount tube 2 remains in claw 12and lower mount tube 3 in claw 13 of lift bracket 10 due to the torquecaused by the weight of carrier 1. FIG. 11 shows a perspective view ofactuator 11 in the first position, with the second hitching device andsecond actuator of the actuating device not being shown for clarity.

[0080] As shown in FIG. 10, the contact of wheel 4 with ground 400however begins to create an opposite torque about tube 2,counterclockwise about tube 2 in the FIG. 10 view.

[0081]FIG. 12 shows a first release step of the golf club carrier 1 fromlift bracket 10 with actuator 11 in a fully extended position. As theactuator 1 extends past the FIG. 10 position, lower tube 3 swings freeof claw 13 due to the torque created by wheel 4 contacting ground 400.Tube 3 moves past finger 113. Frame 9 can also contact ground 400.Bracket 10 may contact bumper 303 as an additional stop. FIG. 13 shows aperspective view of the FIG. 12 release step.

[0082]FIG. 14 shows a second release step of the golf club carrier 1.Once lower mount tube 3 has cleared lower claw 13, the user can rotatehandle 7 in direction M to release upper mount tube 2 from upper claw 12and then pull carrier 1 in direction L.

[0083]FIG. 15 shows the golf club carrier 1 fully released from themotorized golf cart 300.

[0084] To reattach golf club carrier 1 to lift bracket 10 or 110, uppermount tube 2 is positioned into upper claw 12, as shown in FIG. 12, by auser. The user then can move knob 501 upwardly, and switch 500 causesactuator 11 to retract, lifting golf club carrier 1 off ground 400.Alternately, the actuator 11 may begin to retract automatically oncetube 2 is in claw 12, for example by pushing down a paddle actuator orcompleting an electric circuit.

[0085] As wheel 4 begins to lift off ground 400 as shown in FIG. 9, theclockwise torque about tube 2 created by the weight of carrier 1 causesmount tube 3 to move past finger 113 and enter claw 3. Rollers orfriction coating on mount tube 3 may aid in reducing friction betweenfinger 113 and tube 3, so that mount tube 3, “snaps” into lower claw 13.

[0086] It should be understood that carrier 101 and shopping cart 201may have similar hitching devices as that of carrier 1. A lockingdevice, for example, with a key, can be used to lock the carriers 1,101, 201 to the golf cart for security.

[0087] Additional views of the present invention are provided as well.FIG. 16 shows a different perspective view of the FIG. 2 configuration,the golf bags not being shown for clarity. FIG. 17 shows a top view ofthe FIG. 2 configuration. FIG. 18 shows a rear view of the FIG. 2configuration. FIG. 19 shows the FIG. 2 view with the first actuatorjust near the first position.

[0088] Many other types of detachable devices thus are possible toattach to the golf cart using the hitching devices. Wheelchairs andcustomized carriers, such as garden tool carriers for a garden tool setor golf course repair carriers with a course repair set, are possible.In some cases, both actuators can be used to lift a single detachabledevice with a hitching device or devices connected to both hitchingdevices on the golf cart. However, the user should then ensure that thelifting is synchronized.
